The annual Bishop’s Thanksgiving dinner will be served at noon Nov. 22 in the Cenacle in the lower level of St. Paul Cathedral. Meals also will be delivered to those who are homebound. Each year the bishop invites those who are alone on Thanksgiving and Christmas to join him for the traditional turkey and all the fixings. Last year more than 1,600 meals were home-delivered. Usually those who eat at the cathedral number about 140 to about 160, according to Robert Cronin of Catholic Charities, dinner coordinator. Buses will provide transportation to and from the cathedral for those who want to dine with Bishop McManus, who will be the host, along with Catholic Charities. Catholic Charities is looking for more volunteers to deliver the meals to the homebound this year, Mr. Cronin said. Volunteers who want to help with home deliveries of dinners should report by 9:30 a.m. to the Catholic Charities main office at 10 Hammond St. Volunteers to help serve the dinners at the cathedral should report to the cathedral by 11:30 a.m. Volunteers who want more information may call 508-860-2232. Those who wish to make donations to help defray the cost of the dinner may do so by sending contributions to Catholic Charities, 10 Hammond St., Worcester MA 01610.
